Lets Talk EGT'S, and tunes
 

In my 140race i can hit 1400 with an intake and 4" turbo back is anyone else getting this high. Lastly whats everyone running for a dd tune and what kind of mpg's are you seeing. Ive had the chip in for 2 days now and am impressed but the trans seams so hang up in 3rd in 140race but trans dont slip or temp dont rise very fast but make sure i got it pointed in the right direction bc is gone.

thats pretty dang hot, i've seen 1200 or so on mine on the 120 tune, i run 80dd(in traffic) or 100 performance, 120 is nice for highway cruising, MPG's are slightly better actually.. i couldnt give you a number but i'll tell you they went up(if i keep my foot outta it that is).

ya thats why i figured i should see what everyone eles was getting. The guy claimed it had an 4" exhaust. I shouldve measured the down pipe when i had it off the turbo would a stock exhaust let the temps get that hot

Turbo surge
 

I just got my FU chip installed today. What a difference in performance. I was running the 100 performance tune leaving a stoplight and got on it pretty good. I got some turbo surge and was wonder would a ww help this and would this still be considered a mild mod for my FU chip? BTW, love the chip so far. :happy-dancing:

W-W took care of my surge & quite a bit cheaper than a ported housing.:thumbs up yellow:

yes ww should take care of most of the surge im lucky and havent seen it yet knock on wood what kind of egts are you seeing in 140race?

Normal temps.

More power, more fuel. More fuel, more heat.

In 140, I get 1200-1250 tops. Have a 4" dp with 5" exhaust. Haven't seen 1400, and I've romped on it. I see 600-800 drinving normally.

would a stock exhuast cause temps to be that high bc im seeing 300 more than most or could the truck have upgraded injectors?

Highly unlikely that you have modified injectors if the tuning works fine......

There are a lot of things to take into account here:

Ambient temperature
Elevation
Fuel quality
Engine mechanical condition
High pressure oil system "health"
Vehicle weight
Boost/drive pressure leaks


The best thing to do in your case is to put in a straight-through muffler on the stock exhaust system as it's plenty big to support stock injectors and it won't cost you an arm and a leg. My 2000 has a muffler from a 1995-1997 PSD and it's quiet and it was free. The downpipe is stock....at this point, it's certainly not hurting anything.
